Description

CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of and priority to Korean Patent Application No. 10-2023-0062092, filed on May 14, 2023, the entire contents of which are incorporated herein by reference.

TECHNICAL FIELD

The present disclosure relates to a seat control apparatus and a method thereof. More particularly, the present disclosure relates to a technology for controlling a state of a seat based on a user's intent.

BACKGROUND

As technology advances, various components within a vehicle may be operatively connected to one another. A vehicle control apparatus may quickly and accurately provide various functions by performing cooperative control among components for a user's convenience.
In particular, to enhance the convenience of the user who boards a seat in a vehicle, a function of adaptively controlling the state (or location) of the seat is being progressively developed. For example, in a situation where the user gets on or gets off a host vehicle, a technology for enhancing the user's convenience by adaptively changing a location or state of the seat is being developed.
However, as the type of device (e.g., a driving device, and the like) capable of changing the state of a seat is restrictively provided, it becomes difficult to provide a seating state that makes the user's entry and exit as comfortable as possible.

Hereinafter, various embodiments of the present disclosure are described in detail with reference to FIGS. 1-8 .
FIG. 1 is a block diagram showing components of a seat control apparatus, according to an embodiment of the present disclosure.
According to an embodiment, a seat control apparatus 100 may include at least one of a sensor device 110, a driving device 120, a memory 130, a control device 140, or any combination thereof. The configuration of the seat control apparatus 100 shown in FIG. 1 is an example, and embodiments of the present disclosure are not limited thereto. The seat control apparatus 100 may further include components (e.g., at least one of an output device, a communication device, a driving device, an input device, an interface device, or any combination thereof) not shown in FIG. 1 .
According to an embodiment, the sensor device 110 may obtain (or sense) various pieces of information used for driving a vehicle.
The sensor device 110 may include at least one sensor including at least one of a camera, a radar, a light detection and ranging (LiDAR), or any combination thereof.
The sensor device 110 may obtain information about an external object (e.g., at least one of a person, a burden, an obstacle, a structure, or any combination thereof) by using at least one sensor.
The sensor device 110 may obtain information about at least one of a rainwater sensor, a sensor configured to obtain various pieces of information about a host vehicle, or any combination thereof.
Furthermore, the sensor device 110 may obtain information about at least one of the starting states of the host vehicle, the driving speed of the host vehicle, the open-and-close state of at least part of a plurality of doors included in the host vehicle, or any combination thereof.
According to an embodiment, the driving device 120 may include at least one of a motor, an engine, or any combination thereof.
The driving device 120 may change a location (or state) of at least part of a plurality of seats provided in the host vehicle based on a control signal delivered from the control device 140.
For example, the driving device 120 may include at least one of a plurality of motors, a plurality of actuators, a plurality of gears, or any combination thereof, which correspond to a plurality of seats, respectively.
According to an embodiment, the memory 130 may store instructions or data. For example, the memory 130 may store one or more instructions that cause the seat control apparatus 100 to perform various operations when executed by the control device 140.
The memory 130 and the control device 140 may be implemented as one chipset. The control device 140 may include at least one of a communication processor or a modem.
The memory 130 may store information related to states and/or operations of components (e.g., at least one of an engine control unit (ECU), the sensor device 110, the control device 140, or any combination thereof) of the host vehicle.
The memory 130 may store various pieces of information related to the seat control apparatus 100. For example, the memory 130 may store information about the operation history of the control device 140.
The memory 130 may also identify a state of each of the plurality of seats included in a host vehicle at a specific time point.
According to an embodiment, the control device 140 may be operatively connected to the sensor device 110 and/or the memory 130. For example, the control device 140 may control the operation of the sensor device 110 and/or the memory 130.
The control device 140 may identify a user's intent (e.g., intent to get off the host vehicle) who has boarded (or is currently boarding) the host vehicle by using the sensor device 110.
The control device 140, by using the sensor device 110, may obtain information about at least one of the starting states of the host vehicle, the driving speed of the host vehicle, the opening/closing state of a door corresponding to a seat on which the user is sitting, or any combination thereof.
For example, when identifying that the host vehicle is in a non-starting state and a door corresponding to the seat on which the user is sitting is opened, the control device 140 may identify that the user has the intent to get off the host vehicle (i.e., get out of the host vehicle).
Furthermore, when identifying that the host vehicle is not driving (e.g., the driving speed is 0 km/h) and the door corresponding to the seat in which the user is sitting is opened, the control device 140 may identify that the user has the intent to get off the host vehicle.
When identifying that the driving speed is less than or equal to the specified speed (e.g., 3 km/h) and the door corresponding to the seat on which the user is sitting is open, it may be identified that the user has the intent to get off the host vehicle. In this case, the control device 140 may determine that the user's intent satisfies a specified condition.
The above-described embodiment is an example, and embodiments of the present disclosure are not limited thereto. For example, when identifying that a door corresponding to a seat in which the user is sitting is opened in a situation where at least one of the above-described conditions (e.g., a state where the host vehicle is not started, a state where the host vehicle is not driving, and a state where the driving speed of the host vehicle is less than or equal to a specified speed) is satisfied, the control device 140 may identify that the user has the intent to get off the host vehicle.
When the user's: intent satisfies the specified condition, the control device 140 may identify a state (e.g., a real-time state of the seat at a point in time when a door is opened) of the seat corresponding to the user.
The control device 140 may store the state of the identified seat in the memory 130. When the user gets on the host vehicle again later, the control device 140 may use the stored state of a seat to control the seat.
The control device 140 may control the seat by using the driving device 120.
For example, when it is determined that the user's intent satisfies the specified condition, the control device 140 may store the state of the seat in a memory. The control device 140 may then control at least one of a slide location of the seat, a tilt location of the seat, a legrest location of the seat, or any combination thereof based on the state of the seat by using the driving device 120.
The control device 140 may determine whether at least one of a current slide state of the seat, a current tilt state of the seat, a current legrest state of the seat, or any combination thereof, which is stored in the memory 130, is included in a specified area. The specified area may be a value capable of being changed by the user's settings or a setting value set at a point in time when a seat is installed for the first time. The specified area may include an area within a specific range (or distance or angle) based on a specific point within the host vehicle. For example, the control device 140 may identify a parameter, which is not included in the specified area, from among a plurality of parameters (e.g., a slide state, a tilt state, and a legrest state) included in the state of the seat. The control device 140 may control the identified parameter such that the identified parameter is included in the specified area. In other words, when it is identified that the slide state of the seat exceeds a specific value (e.g., 30 mm) based on the specific point, the control device 140 may control the slide location such that the slide location of the seat is changed within a specific value. Additionally, when it is identified that the tilt state of the seat exceeds a specific angle (e.g., 10 degrees) based on the specific point, the control device 140 may control the tilt location of the seat such that the tilt location is changed within a specific angle. Furthermore, when it is identified that the legrest state of the seat exceeds a specific angle (e.g., 25 degrees) based on the specific point, the control device 140 may control the legrest location of the seat such that the legrest location is changed within a specific angle. For example, when it is identified that the legrest state of the seat is less than a specific angle based on the specific point, the control device 140 may control the legrest location of the seat such that the legrest location is changed to a specified angle (e.g., 0 degrees).
The control device 140 may generate an absolute value of the control amount (e.g., a distance control amount for a slide location change, an angle control amount for a tilt location change, or an angle control amount for a legrest location change) for seat control based on the state of the seat. Additionally, the control device 140 may control the location of the seat based on the generated control amount.
The control device 140 may generate at least one of a target slide location, a target tilt location, a target legrest location, or any combination thereof for controlling the seat based on the state of the seat. Unlike an embodiment in which an absolute value is generated and a seat is controlled based on the absolute value, in this case, the control device 140 may control the seat until the generated target location.
The control device 140 may set priorities for controlling a slide location, a tilt location, and a legrest location. For example, after the control of the slide location of the seat is terminated, the control device 140 may terminate control of a tilt location and a legrest location together. Even after the slide location of the seat is terminated, the control device 140 may continuously control the tilt location and the legrest location.
After the control device 140 determines that a user has the intent to get off the host vehicle to control the seat as described above, the control device 140 may determine whether the user has the intent to get on the host vehicle again.
When it is identified that the user gets on (or intends to get on) the host vehicle again, by using an open/closed state of a door identified by using the sensor device 110 after the user gets off the host vehicle, the control device 140 may control at least one of a slide location of the seat, a tilt location of the seat, a legrest location of the seat, or any combination thereof based on the state of the seat stored in the memory 130.
The control device 140 may identify a slide state among seat states stored in the memory 130, and may control the seat such that the slide location of the seat is the same as the stored slide state. In other words, when the user gets off and gets on the host vehicle again, the control device 140 may omit the control of a tilt location or a legrest location, and may only control the slide location such that the slide location becomes the same as a location before the user gets off the host vehicle.
The control device 140 may also identify a tilt state and a legrest state among seat states stored in the memory 130. When the user's riding intent is identified, the control device 140 may control a tilt location and a legrest location based on the setting state of the tilt and legrest control. For example, when the tilt and legrest control is set to be in an on state when the user gets on the host vehicle, the control device 140 may control the seat such that the tilt location and the legrest location are the same as those in the tilt state and legrest state stored in the memory 130, while controlling the slide location.
Furthermore, even when it is determined that the user's intent satisfies a specified condition, based on at least one of an operating state of at least one of a plurality of seats of the host vehicle including a seat, a passenger state in the host vehicle, or any combination thereof, the control device 140 may not perform seat control or may terminate control of the seat midway.
For example, when at least one of a plurality of seats of a host vehicle including a seat that operates in a walk-in mode (or, when at least one of a plurality of seats is operating in real-time), when it is identified that an infant gets on the host vehicle, and/or when it is identified that there is an infant seat in at least one of a plurality of seats of the host vehicle, the control device 140 may terminate (or stop or not perform) control of the seat.
The components of the seat control apparatus 100 shown in FIG. 1 is an example, and embodiments of the present disclosure are not limited thereto. For example, the seat control apparatus 100 may further include a communication device (not shown).
According to an embodiment, the communication device may establish a communication channel (e.g., wireless communication channel) between the seat control apparatus 100 and an external device (e.g., an audio-video-navigation (AVN) device). Additionally, the communication device may support communication through the established communication channel. For example, the communication device may include one or more communication processors which are operated independently of the control device 140 (e.g., an application processor) and support direct (or wired) communication or wireless communication.
The communication device may also include a wireless communication module (e.g., a cellular communication module, a short-range wireless communication or module, a global navigation satellite system (GNSS) communication module) or a wired communication module (e.g., a local area network (LAN) communication module or a power line communication module). The corresponding communication module among these communication modules may communicate with an external device through a first network (e.g., a short-range communication network such as Bluetooth, wireless fidelity (WiFi) direct or infrared data association (IrDA)) or a second network (e.g., a legacy cellular network, 5G networks, next-generation communication networks, Internet, or telecommunication networks such as computer networks (e.g., LAN or WAN)) included in a network. The above-described kinds of communication modules may be integrated in one component (e.g., a single chip) or may be implemented with a plurality of components (e.g., a plurality of chips) which are independent of each other. Also, the communication device and the control device 140 may be implemented as a single chip.
The control device 140 may also communicate with an external device (e.g., an external controller distinct from the control device 140) by using the communication device. For example, the control device 140 may receive various pieces of information from an external device by using the communication device.
The control device 140 may also receive information, which is obtained by an external device connected to the sensor device 110 by using the sensor device 110, using the communication device. In other words, the control device 140 may obtain information about at least one of the starting states of the host vehicle, the driving speed of the host vehicle, the open/closed state of the door, or any combination thereof by using the sensor device 110. Alternatively, the control device 140 may receive the information, which is obtained by an external device connected to the sensor device 110 by using the sensor device 110, using a communication device.
FIG. 2 is a conceptual diagram showing a configuration of a seat, according to an embodiment of the present disclosure.
According to an embodiment, a seat 201 may be changed to various locations based on the control of a seat control apparatus (e.g., the seat control apparatus 100 in FIG. 1 ). For example, the seat control apparatus may control a location of the seat 201 by using a driving device (e.g., the driving device 120 of FIG. 1 ).
The seat control apparatus 100 may control a slide location of the seat 201 by controlling a slide device 210. The seat control apparatus 100 may move the seat 201 to the left or right by using the slide device 210 in a direction in which the seat 201 illustrated in FIG. 2 is viewed.
The seat control apparatus 100 may also control a tilt location (e.g., an angle of a cushion 292 included in the seat 201) by controlling at least one tilt device 222 or 224.

FIG. 3 is a conceptual diagram illustrating an operation of a seat control apparatus, according to an embodiment of the present disclosure.
Referring to reference number 310, according to an embodiment, a seat control apparatus (e.g., the seat control apparatus 100 of FIG. 1 ) may allow a seat 301 to be in a relaxation mode by using a driving device (e.g., the driving device 120 in FIG. 1 ). A relaxation mode may be defined as a combination of “relax,” which means that the user relaxes, and “position,” which means the posture of the seat. A relaxation mode may refer to an operation mode (or state) of a seat implemented so that the user may sit relatively comfortably and rest.
Based on a specified axis 350 of the seat 301, the relaxation mode may be an operating mode in which a reclining angle, a legrest angle, and a tilt angle of the seat 301 are larger than those in a general mode (e.g., a mode in which a vehicle that a user boards is moving, and the like). Additionally, in the relaxation mode, a slide location is moved to the front side of the host vehicle compared to the general mode.
Referring to reference number 320, according to an embodiment, when it is determined that the user has the intent to leave the seat 301 and get off the host vehicle, the seat control apparatus 100 may allow the seat 301 to be in a getting-off mode by using a driving device.
For example, based on the specified axis 350 of the seat 301, the getting-off mode may be an operating mode in which a reclining angle, a legrest angle, and a tilt angle of the seat 301 are smaller than those in the relaxation mode. Additionally, a slide location is moved further to the rear side of the host vehicle compared to the relaxation mode.
To control the location of the seat 301 from the relaxation mode to the getting-off mode, the seat control apparatus 100 may control a legrest location of the seat in a first direction 322. The seat control apparatus 100 may also control a tilt location of the seat in a second direction 324, and may control a slide location of the seat in a third direction 326.
Referring to reference number 330, according to an embodiment, the seat control apparatus 100 may allow the seat 301 to be in the getting-off mode. Afterward, when it is determined that the user has an intent to get on the host vehicle again and sit in the seat 301, the seat control apparatus 100 may allow the seat 301 to be in a getting-on mode by using the driving device.
For example, based on the specified axis 350 of the seat 301, the getting-on mode may be an operating mode in which a slide location of the seat 301 is relatively moved to the front side of the host vehicle compared to the getting-off mode according to reference number 320.
To control a location of the seat 301 from the getting-off mode to the getting-on mode, the seat control apparatus 100 may allow a slide location of the seat in a fourth direction 336.
Although not shown in FIG. 3 , when controlling a location of the seat 301 from the getting-off mode to the getting-on mode, the seat control apparatus 100 may control the legrest location and/or tilt location together with the slide location. The legrest location and/or tilt location may be selectively controlled depending on the user's settings together with the control of the slide location.
FIG. 4 is a conceptual diagram illustrating an operation of a seat according to a control of a seat control apparatus, according to an embodiment of the present disclosure.
According to an embodiment, a seat control apparatus (e.g., the seat control apparatus 100 in FIG. 1 ) may control a tilt location and/or legrest location of a seat 401 by using a driving device (e.g., the driving device 120 in FIG. 1 ). In FIG. 4 , an embodiment in which a seat control apparatus 100 controls a tilt location of the seat 401 is shown. However, this is an example, and the embodiment may be applied to control a legrest location and/or slide location. The seat control apparatus 100 may selectively apply a control amount for controlling the seat 401.
The seat control apparatus 100 may identify a current state (e.g., at least one of a current slide state, a current tilt state, a current legrest state, or any combination thereof) of the seat 401. The seat control apparatus 100 may also control the location of the seat by a specified value (e.g., a specified distance or a specified angle) from a current state.
For example, the seat control apparatus 100 may allow a location of the seat 401 to move to a target location regardless of the current state of the seat 401. The seat control apparatus may allow the tilt location of the seat 401 to correspond to a target point 450. The target point 450 may correspond to an intermediate point of a tilt location range 405 controllable by the seat control apparatus 401.
The seat control apparatus 100 may also classify the controllable tilt location range 405 into a first section 410 and a second section 420 based on the target point 450.
For example, immediately before controlling the seat 401, when it is determined that the tilt location of the seat 401 is included in the first section 410, the seat control apparatus 100 may allow the tilt location of the seat 401 to correspond to the target point 450.
Furthermore, immediately before controlling the seat 401, when it is determined that the tilt location of the seat 401 is included in the second section 420, the seat control apparatus 100 may allow the seat 401 to correspond to the target point 450 or may not control a tilt location.
FIG. 4 illustrates that the target point 450 is a single target point. However, the target point 450 shown in FIG. 4 may be one of a plurality of target points set such that the seat control apparatus 100 controls the tilt location.
The seat control apparatus 100 may also identify a maximum point and a minimum point of the tilt location range 405 that is capable of being controlled. The seat control apparatus 100 may set a point between the two points as a target point.
Immediately before controlling the seat 401, when a tilt location of the seat 401 is included within any point between two points from the minimum point of the controllable tilt location range 405, the seat control apparatus 100 may control the tilt location of the seat 401 to the minimum point.
Furthermore, immediately before controlling the seat 401, when the tilt location of the seat 401 is included within one point between two points from the maximum point of the controllable tilt location range 405, the seat control apparatus 100 may control the tilt location of the seat 401 to the maximum point or any one point.
